We have a hosted site on GoDaddy and Saturday night our site was apparently hacked. Modules that had been expired for years were on our front page as well as modules that were originally on other pages. 3 new superuser accounts were created and I think our login skin got changed since it no longer pops up but ioverlayes a potion of the screen with the only option to MaxClose. Any ideas on what secyrity vulnerabiltiy they exploited? I cna find nothing on it, other than to upgrade. What should the login skin be?
